Answer 1

 using (Stream stream = ... fetch the stream from somewhere) { byte[] buffer = new byte[stream.Length]; stream.Read(buffer, 0, buffer.Length); File.WriteAllBytes("foo.pdf", buffer); } 

and if this RESTful service says HTTP, you can use WebClient :

 using (var client = new WebClient()) { client.DownloadFile("http://example.com/api", "foo.pdf"); }

I had this situation, and I decided to use iTextSharp to create a PDF file and save it to disk.

 public void GeneratePdf(string htmlPdf) { var pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f); var htmlparser = new HTMLWorker(pdfDoc); using (var memoryStream = new MemoryStream()) { var writer = PdfWriter.GetInstance(pdfDoc, memoryStream); pdfDoc.Open(); htmlparser.Parse(new StringReader(htmlPdf)); pdfDoc.Close(); byte[] bytes = memoryStream.ToArray(); File.WriteAllBytes(@"C:\file.pdf", bytes); memoryStream.Close(); } }
